Payout ratios

Dividends are usually paid out of company earnings. If a company is paying more than it earns, then the dividend might become unsustainable - hardly an ideal situation. So we need to form a view on if a company's dividend is sustainable, relative to its net profit after tax. China Hanking Holdings paid out 39% of its profit as dividends, over the trailing twelve month period. This is a middling range that strikes a nice balance between paying dividends to shareholders, and retaining enough earnings to invest in future growth. Plus, there is room to increase the payout ratio over time.

Another important check we do is to see if the free cash flow generated is sufficient to pay the dividend. China Hanking Holdings paid out 8.9% of its free cash flow as dividends last year, which is conservative and suggests the dividend is sustainable. It's encouraging to see that the dividend is covered by both profit and cash flow. This generally suggests the dividend is sustainable, as long as earnings don't drop precipitously.

Dividend Volatility

From the perspective of an income investor who wants to earn dividends for many years, there is not much point buying a stock if its dividend is regularly cut or is not reliable. The first recorded dividend for China Hanking Holdings, in the last decade, was eight years ago. Although it has been paying a dividend for several years now, the dividend has been cut at least once, and we're cautious about the consistency of its dividend across a full economic cycle. During the past eight-year period, the first annual payment was CN¥0.021 in 2012, compared to CN¥0.073 last year. Dividends per share have grown at approximately 17% per year over this time. The growth in dividends has not been linear, but the CAGR is a decent approximation of the rate of change over this time frame.
